Delta X G2/12 RF Signal Detector and Counter-Surveillance System

The Delta X G2/12 is a professional counter-surveillance system developed for detecting hidden RF transmitters, wireless surveillance devices, and suspicious signal activity across a wide modern spectrum. Designed for serious TSCM work, it combines real-time spectrum analysis, long-term monitoring, signal classification, and probe-based inspection in a portable computer-controlled platform.

This model is built to detect a broad range of transmission types, including analog and digital signals, continuous or intermittent activity, audio or video transmitters, and encrypted or unencrypted devices. It is suitable for locating hidden surveillance equipment operating on standards such as GSM, 3G, 4G/LTE, 5G under 12 GHz, Bluetooth, Wi-Fi, and DECT.

For users who need more than a basic RF detector, the Delta X G2/12 offers a structured and highly detailed approach to signal detection, analysis, and logging. It is designed for both active sweeps and continuous monitoring, making it suitable for professional inspections, secure environments, and vehicle tracker checks.

Wide Frequency Coverage and Real-Time Detection

The system covers a frequency range of 9 kHz to 12 GHz, giving it the reach needed for modern wireless threat detection. Its real-time spectrum analysis is especially useful for identifying short-burst transmissions that can be missed by simpler detectors, including activity associated with Wi-Fi, Bluetooth, and mobile devices.

With a sweep speed of 3–4 GHz per second and a response time of 3–4 seconds, the Delta X G2/12 is designed to react quickly in dynamic RF environments. This helps users detect intermittent transmissions and signals that appear only briefly or at irregular intervals.

The unit also features automatic antenna selection to maximize sensitivity across different frequency bands. According to the supplied specifications, it delivers 20 to 50 times higher sensitivity and detection range than conventional RF detectors and near-field receivers.

Designed for Professional TSCM Work

The Delta X G2/12 is not limited to standard over-the-air RF sweeps. Using the included multifunctional probe, it can also detect illegal transmission of information through AC power cables, telephone lines, Ethernet lines, alarm wires, and infrared. This expands inspection capability beyond wireless-only detection and supports more complete technical surveillance countermeasure procedures.

It can also detect hidden transmitters operating within other signal spectrums through signal accumulation, helping users identify suspicious activity that may otherwise be masked by surrounding RF traffic.

For practical fieldwork, the system includes several dedicated operating modes that support different inspection tasks and monitoring strategies.

Main Detection and Monitoring Modes

• Instant Detection for rapid identification of active RF threats
• Guard Mode for long-term monitoring with false alert suppression
• Signal Localization for helping locate active transmitters
• GPS Tracker Detection for identifying trackers in vehicles using mobile bands
• Probe Scanning for checking wired infrastructure and infrared paths
• Detection Log Review for examining stored spectrum activity and alerts
• Signal Analysis and Demodulation for identifying active transmissions

Advanced Signal Recognition and Threat Assessment

One of the key strengths of the Delta X G2/12 is its ability to do more than simply show signal presence. The system supports automatic recognition and classification of digital and analog signals, with threat level assignment to help users prioritize suspicious activity.

Its threat evaluation process uses reference traces and custom thresholds and takes into account signal strength and bandwidth. The supplied information also states that this process remains effective even with frequency-hopping transmissions, which can be difficult to assess with simpler equipment.

The system can analyze signals individually and present higher-risk activity separately from safe or expected signals. This is particularly useful in busy wireless environments where legitimate infrastructure can otherwise make interpretation difficult.

Known Signals Table and Interference Management

The Known Signals table helps distinguish between harmless and potentially dangerous frequencies. Safe signals such as TV, FM, police, and emergency bands can be imported and excluded from attention, allowing operators to focus on unknown or suspicious transmissions.

The Delta X G2/12 also supports interference filtering, enabling users to ignore noise from routers, mobile towers, and other expected RF sources by adjusting thresholds. In addition, mobile band configuration can be adapted to the country of operation, which improves practical deployment in different regions.

24/7 Monitoring and Data Logging

For long-term security monitoring, the Delta X G2/12 supports 24/7 RF environment monitoring with automatic logging. All spectrum traces and alerts can be recorded for real-time review or later analysis, helping users identify intermittent devices or remotely activated transmitters that may not be active during a short inspection window.

The product information specifies unlimited signal storage support, while the technical section lists storage for 24-hour logging: < 24 GB. This makes the system suitable for continuous monitoring workflows where maintaining a detailed activity history is important.

Signal activity can be reviewed through alert charts, allowing users to inspect the duration and frequency of events and revisit specific moments by clicking on the graph. This historical visibility is valuable when validating whether a signal is routine, environmental, or potentially suspicious.

Visual Analysis Tools

The software includes multiple visual formats to support interpretation and comparison of RF activity:

• Spectrogram
• Persistence
• Waterfall
• Alert graphs

Users can compare live and past measurements and adjust graph time density from 2 minutes to 6 hours. Sorting and filtering are also supported within the signal database, and detailed reports can be exported when documentation is required.

Audio Demodulation and Localization Support

The Delta X G2/12 supports audio demodulation in FM, AM, USB, LSB, and CW, with adjustable bandwidth from 3 to 240 kHz. This gives trained users additional tools for analyzing active transmissions during inspections.

During bug localization, the software provides visual and audible notifications to guide the operator. The Hold Max Danger function can lock in the highest-risk signals during movement, which is useful when scanning an area and trying to maintain focus on the most relevant activity.

Portable Field-Ready Design

Although it is a professional system, the Delta X G2/12 is designed for portability. The main unit connects securely to a laptop or tablet, allowing mobile use in the field. Magnetic mounts fix the laptop or tablet to the main unit, and side handles improve portability during inspections. All antennas attach directly to the main unit for a more integrated setup.

The system is powered via USB from a laptop or tablet, which simplifies deployment and supports mobile operation without a separate power arrangement mentioned in the supplied material.

The unit itself measures 33.5 x 26 x 6 cm and weighs 3.4 kg without a laptop.
